Evaluation of an automated tabletop blood biochemical analyzer for the veterinary clinical pathology laboratory.
The importance of accurate quantitative blood biochemical analysis for the diagnosis and management of disease is recognized by most veterinarians. In recent years, several biochemical analyzers have become available for the veterinary market. One of these analyzers was evaluated for its suitability in measuring several biochemical variables--alkaline phosphatase, urea nitrogen, creatinine, glucose, alanine transaminase (dog and cat only), and aspartate transaminase (horse only)--in dogs, cats, and horses. Instrument within-day precision ranged from 1.0 to 7.1%, and between-day precision ranged from 1.6 to 7.4%. During the 6-month period of the study, the analyzer required recalibration for only 1 analyte (creatinine). Concentrations of individual analytes were similar when blood (collected in anticoagulant), plasma, and serum were assayed in parallel. The accuracy of the analyzer, as measured by correlation to a reference method, ranged from 0.861 for creatinine in horses to greater than 0.950 for each of the other analytes in the 3 species. Mean values for each analyte were similar, except for alkaline phosphatase, which had consistently lower values by use of the analyzer method. A data base was established for reference values in each species.
